Summary
Stickler syndrome is a genetic connective tissue disorder affecting eyes, face, skeleton, and hearing. Early diagnosis and multidisciplinary care are crucial for managing this collagen-related condition.
Area of Science:
- Genetics and Molecular Biology
- Rheumatology and Orthopedics
- Ophthalmology
Background:
- Stickler syndrome is an autosomal dominant connective tissue disorder.
- Characterized by ocular, orofacial, skeletal, and auditory features.
- Estimated prevalence of 1:10,000.
Observation:
- A case report of a girl with salient features of Stickler syndrome.
- Presented at birth with Pierre Robin sequence and bilateral exophthalmos.
- Developed high myopia, vitreous gel abnormalities, joint hypermobility, and articulation issues.
Findings:
- Stickler syndrome is linked to mutations in collagen genes (COL2A1, COL11A1, COL11A2).
- Subclassified into types 1, 2, and 3 with significant clinical overlap.
- Mild cases may go undiagnosed due to overlapping symptoms.
Implications:
- Genetic subclassification aids in understanding disease heterogeneity.
- Early diagnosis is essential for timely intervention.
- A coordinated multidisciplinary follow-up approach is recommended for optimal patient management.
